Inside the morphed container are three inline scripts: set marker A, then a script that deliberately throws, then set marker B (after the thrower). If scripts run after a morph AND one bad script does not abort the batch, both markers end up set.
Update count: 0
Marker A: unset
Marker B (set by a script AFTER the throwing one): unset
